420 Steel Guide
We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.
BG-42 Slightly larger in carbon, chrome and moly than ATS-34. Must be cast and heat treated at very high and precise temperatures. Can be used at very excessive hardness, similar to RC 64-sixty six.
Buck Knives and Gerber Knives use 420HC extensively.420A (420J1) and 420B ( 420J2 ) are economical, extremely corrosion resistant stainless steel grades. Knife manufacturers use this materials in price range knives, also in diving knives because of its excessive resistance to corrosion.
The term surgical stainless steel is meaningless, as a result of there’s a couple of stainless steel used for surgical devices. Other components added to steel to improve hardness, toughness and put on resistance are cobalt, manganese, molybdenum, nickel and vanadium.

Series—austentic Chromium-molybdenum Alloys
- Third-generation powder metallurgy technology steel.
- The following Powder Metallurgy steels contain very excessive ranges of Chromium, which at 18–20% produces a metal matrix that’s highly corrosion resistant.
- Chromium, molybdenum, vanadium, and tungsten are added for glorious sharpness and edge retention.
- Developed for knife blades requiring good corrosion resistance and very excessive hardness for wonderful wear resistance.
Our stainless production range
420 sequence contain a number of varieties with numerous carbon content between .15% and .40% this metal grade is widely used to make high finish razor blades, surgical scalpels and so on. It obtains about fifty seven HRC after appropriate heat therapy. 420HC ( 420C ) is a higher carbon content material 420 stainless. The HC stands for “high carbon” and it may be brought to a better hardness than common 420 and should not be mistaken for it.
Hardens and tempers to HRC, the place it greatest balances edge holding and toughness. Due to its alloying concept, this metal presents extremely excessive wear resistance and high corrosion resistance.
This steel in its unhardened or tempered state is simple to form by forging or grinding. It can then be warmth-handled to hardnesses appropriate for knives. High carbon metal takes a superb edge, nevertheless it has no corrosion resistance. Most knives today are produced from some type of stainless steel.
Mechanical Properties At Room Temperature
Stainless steel is made by including 12% or extra chromium to the alloy. It is somewhat more durable to work with and sharpen, but it has the benefit of corrosion resistance. Because of this, it’ll maintain an edge longer in wet circumstances.
We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
